If you are still looking at this I can tell you that I purchased a 10/4 this summer and I love it. I am on the chesapeake and have no problem getting going. Mine is missing a centerboard so it doesnt track all that well and i am probably limited to about 30 degrees off the wind when trying to go to winward. You cant beat the amount of room you get on this for a 25' boat. 5 - 10 knots wind speed gets you a nice leisurely sail. 10-15 and you can really get going. 15-25 i have to reef the main, but then she flies (relatively, probably not going to win any races). Never been out in anything over 25 knots.
